This Bedford OYD GS 4×2 Truck was on display at the Imperial War Museum Duxford.
The Bedford OY is an army lorry built by Bedford for the British Armed Forces and introduced in 1939. It was based on Bedford’s O-series commercial vehicles with a modified front end and single rear tyres.
I have a Bolt Action 28mm Home Guard Armadillo Improvised Armoured Vehicle based on a Bedford OYD chassis.
In 15mm I have the same Bedford OYD based Armadillo Improvised Armoured Vehicle from SDD.
